Quintessa (TLK)
| The name or term "Quintessa" refers to more than one character or idea. For a list of other meanings, see Quintessa (disambiguation). |
- Quintessa is a Transformer from The Last Knight portion of the live-action film series continuity family.

Quintessa is a mysterious and powerful space sorceress. The self-described "Prime of Life", she created the Knights of Iacon, Optimus Prime, and the Infernocons and considers Cybertron to be hers to command.
She's also been referred to as "The Great Deceiver", though, so how much of what she says is actually true may be up for debate.

![]() Spoiler warning: Plot details for Transformers: The Last Knight (film) follow. |

After Optimus Prime killed Quintessa's bounty hunter Lockdown, he flew off into space in search of his creators to force them to leave the Earth alone. He soon shut down and rusted from being in space for so long, but at that moment Cybertron's gravity was strong enough to pull him in and the planet's atmosphere undid his rusting, as he finds out that Cybertron is being rebuilt and in far better condition than when he last inhabited it. Optimus sees Quintessa and charges at her to slaughter her with his sword but Quintessa blasts him with an electric energy wave and subdues him with automatic chains. Quintessa reveals that she is Optimus Prime's creator and chastises him for allegedly destroying his home world Cybertron. Optimus objects that Megatron is responsible for the damage done before Quintessa introduces a red virus into his mind that corrupts him so that he obeys her command to help seek an ancient staff stolen from her by her 12 guardians. Quintessa then dubs him "Nemesis Prime".
